Defining Active Users and Reactivation Dynamics

In this episode of Run the Numbers, CJ Gustafson sits down with Vanna Krantz, former CFO of Disney+ and Grindr, to explore what it takes to lead finance through massive inflection points. Vanna reflects on building Disney+’s subscription model from scratch under Bob Iger’s leadership and the pressure of launching a global product with no precedent. She discusses forecasting as both science and art, and the importance of appreciating high-stakes moments amid chaos. Shifting to Grindr, Vanna breaks down how the company went public with remarkable efficiency—boasting 40% EBITDA margins and under 200 employees—and how she modeled for a user base that consistently churns and returns. She also opens up about career longevity, work-life balance, and helping women find sustainability and acceleration in leadership.
